Then in emacs in the project: cider-connect-clj | localhost | <the port it suggests>
In the repl: user> (start)
In the browser: localhost:4000
If restart needed after compilation pblm:
(tools-ns/refresh)
(start)

Start Datahike-frontend client

In the shell: npx shadow-cljs server
In IntelliJ's REPL: (shadow/repl :main)
If you want to use emacs then: cider-jack-in-cljs

You might need to compile the js code here: http://localhost:9630
The nrepl is server in listening on port 9000

Datahike-server

You need to start a Datahike server as well (https://github.com/replikativ/datahike-server) on the 'admin-endpoitns' branch. It is expected to listen on port 3000.

Current status

• It is still very early work.

• Transacting works only when you are on the :eavt Datoms view. (I.e. on the view appearing after a query and showing each entity on a specific row, transactions do not work yet.)

• Only query_pull type queries work.

• Queries seem to have issues when the 'where' expression has multiple clauses.
